[realXtend] b2rex release 1.0rc1
Hi! I've released a new version of b2rex, adapted for blender 2.57 and with a lot of improvements regarding logic and more specific tundra support. This includes a state machine generator for opensim, component editor for tundra: https://sim.lorea.org/pg/pages/view/492/ (state machine editor) https://sim.lorea.org/pg/pages/view/490/ (tundra support) Knet python support was developed for this release, but it didn't make it into this release. Interested people can find the library inside the b2rex code. I've also generated api docs for b2rex, as well as some extra manual documents regarding hacking b2rex and code structure: https://sim.lorea.org/pg/pages/view/514/ https://sim.lorea.org/pg/pages/view/515/ https://dev.lorea.org/%7Ecaedes/b2rex_api/ Also, some things where improved regarding connection to windows servers where most beta testers where experiencing problems, but there may still be some problems since I haven't been able to replicate the problem myself, and couldn't have a steady test server, if someone having problems can arrange a stable access for me I will do my best to fix any problems. Enjoy and greetings! p. signature.asc Description: OpenPGP digital signature
Re: [realXtend] [b2rex] Could b2rex upload a dependence package to github?

At the moment release packages come with all dependencies, that's why they are a bit bigger. They could be packaged separately (I will do it for next release - thx for the idea!) but at the moment you will find them at scripts/b2rexpkg/libs on the releases. The only dependencies that don't come at the moment with the release are python and greenlets because they include os specific binary components, I will be investigating how to include or replace them, but it's tricky because both os and architecture (32 or 64 bit) affect the binaries.

Re: [realXtend] Re: [b2rex]Need help on b2rex. (sorry for a mistake in the previous send)
Hi With the help of MasterJ's server, I found what was going on and fixed it (some problem with xmlrpc connection on login getting stuck). The changes are already in the b2rex github repo, but also require updating the pyogp library so it may be difficult to update for most ppl. I'm now fixing a few last bugs for releasing a new version tomorrow, so probably best is to wait for the new release package. Greetings and thx to all who have tested and reported on this release.

If things go right, the terrain should start loading a few seconds after
the connection turns on. In this case it looks like it's trying to
connect but it's not clear why it doesn't go on. Maybe you could take a
look at the b2rexpkg/simrt.py, and in the line (around line 145):
print("LOGIN WITH", login_params)
change it to:
print("LOGIN WITH", login_params, loginuri)
in order to see the loginuri the agent is using.

This is ok. Looks like you run b2rex before and the connection agent
kept running, thus the second time it can't start it, but it's ok
because the other one can do the job (b2rex connects to the old one
anyways). When you disconnect the first agent disconnects and quits and
so the next time everything is ok (the error you see is an error trying
to open a second process on port 2 which is where the b2rex agent
listens).

This was not a good idea :). That path is hardcoded to localhost 2
because that's where the b2rex connection agent runs, which is a
different process, but the agent was running ok, and the connection to
it are all right too, since we saw before it gets to the LOGIN_WITH log,
which means the agent managed to get the connection parameters from
blender, the fact that the agent quits when turning the RT button off
also illustrates this.

Mmm, for the logs and similar reports from other people, I would say it
may be a problem due to grid mode being configured. Possibly all my
tests (my own public server, my local server and the realxtend virtual
expo world). If someone can provide a server configured in grid mode I
can probably test myself and see what's up, otherwise I have to
configure it myself and it can take some longer.
Another possibility is connections are getting stuck on xmlrpc. B2rex
comes with a patch needed at least on my os (b2rex/patches/patch01.patch).

See the point above, as far as I can tell, b2rex and blender are working
properly, but b2rex gets stuck in the login process and the only reason
I can think of right now is grid configuration in taiga which I didn't test.

I think it would be better if I can debug connection to a server in grid
mode.

xmlrpc is included with python. about other packages I might have

The terrain plane appears after connecting and then should start downloading height blocks (as in the following video: https://sim.lorea.org/pg/videolist/watch/464). I don't understand exactly what you mean about the ogre element, but it is unrelated to b2rex atm (at least to server connecting). > possible it's because b2rex use others ports and we must allow them > open yes, actually I forgot about this in my description. Just after clicking on the RT button, the agent will start up and open a local port so it can communicate with blender. The port is TCP 2 and in my windows vista, I did get a dialog from the firewall warning me about the port open, I allowed the port and then b2rex could go on connecting. Depending on your firewall settings, you might not get this kind of dialog and may need to open manually, otherwise, it may be that the agent is not starting, in this case something should show up in the blender windows console output.

Re: [realXtend] Re: b2rex release 0.8: real time connection and blender2.5 support
Hi! Ok, to all windows testers (MasterJ, PatrickDutoit and Bill), I have successfully run b2rex on windows vista following the instructions from the manual. Since some steps may not be so clear (although they are ok), here goes my report on what I've done with remarks that may be useful about different steps and internal workings. This is an install on windows vista 32 bits. 1- install python2.6: http://www.python.org/ftp/python/2.6/python-2.6.msi (i chose the default path c:\python26, where b2rex explicitly searches, so it may help, otherwise b2rex has a system to find installed python2.6 on windows, but it's basically untested) 2- install greenlets: http://pypi.python.org/packages/2.6/g/greenlet/greenlet-0.3.1.win32-py2.6.exe#md5=d864adfd6a3b057267fb7d2156a62361 3- get blender: http://www.blender.org/dl/http://download.blender.org/release//Blender2.56abeta/blender-2.56a-beta-windows32.zip and unpack somewhere 4- get b2rex: https://github.com/downloads/b2rex/b2rex/b2rex-0.8.zip, unpack, and move everything under b2rex-0.8/scripts/ to blender addons folder after this, open blender, enable ogre exporter, then enable b2rex. at this point, like some other people, I'm getting a notice from windows saying: "An application has made an attempt to load the C runtime library incorrectely" which doesn't seem to affect b2rex (no idea what's going on). I can still save user settings, restart blender and it will stay enabled and the error keeps appearing on blender start. Afterwards, I have configured access to the test server at sim.lorea.org, using https://sim.lorea.org/xml-rpc.php as login url (its a special url different to what you would use connecting to opensim, but this is not relevant). As user I used old login method "caedes caedes". Note everyone can test on the test server, instructions at (any other server should work too, but in doubt, b2rex test server works for sure): https://sim.lorea.org/mod/threaded_forums/topicposts.php?topic=425&group_guid=5 Next, I can connect with the "RT" button, note if the "safe mode" is enabled (default) you will not see changes in blender unless you interact with it (so you need to click on the 3d view or something), safe mode can be disabled at (low :)) risk of crashes but its nicer because blender updates automatically. I noticed there is one part of the setup which is not documented, which is installing the imagemagick tools and setting up the tools path in b2rex, but this will not impact you until you have successfully connected and can see the terrain and whatever rex objects you may have in the region. To install imagemagick, I got: http://www.imagemagick.org/download/binaries/ImageMagick-6.6.8-6-Q16-windows-static.exe (you only need the "convert.exe" tool, but they only seem to provide the whole package), installed it at c:\imagemagick (easier to type later on) and setup the tools path in the b2rex settings so it can find convert.exe, which allows textures to be converted before importing into blender (note, as said, b2rex will still work without these tools but will not be able to load images). Hope this helps, and greetings and thx to all the people who so far tested b2rex Pablo signature.asc Description: OpenPGP digital signature

For the moment b2rex will connect to just one region. It will import rex objects, materials and textures. this is how the virtual expo world looks when "opened" in blender: https://sim.lorea.org/pg/photos/view/445/virtual-expo-world-1 > > I'm interested in trying this new updated version.

The server shouldn't need any special config other than that necessary to allow normal clients (like naali or hippo) to connect, so both grid and region should work, authentication of both "firstname secondname" and "user@server:port" is supported.

[realXtend] b2rex release 0.8: real time connection and blender2.5 support
Hi! B2rex 0.8 has been released, featuring real time connection to taiga/opensim server and support for blender 2.5. https://github.com/downloads/b2rex/b2rex/b2rex-0.8.zip There is a new manual describing the current capabilities of b2rex: https://sim.lorea.org/pg/pages/view/438/ About the real time connection, this means now blender can connect to the sim server as a native client, with full access to the protocol and capabilities to import rex objects on the fly, move, rotate, scale objects, manage permissions, reparent, upload new objects, materials and textures, some inventory management... No support for prims or editing assets yet (they have to be reuploaded with a new uuid). The connection is done through an agent module, which can be an external program or run within the blender process, and also streamlines the protocol into more simple editor commands, so it should be straightforward to adapt to the tundra protocol, or to emit the same messages from naali without the need to understand the underlying protocol at all. The following diagram tries to illustrate the 3 possibilities: https://dev.lorea.org/~caedes/agent-diagram.png. For the moment I have implemented the first and second cases (for blender 2.5 and blender 2.4). Regarding the support for blender 2.5 and blender 2.4, development has switched completely to blender 2.5, and blender2.4 still works to a certain extent although this release is only for blender2.5, and support for blender 2.4 will be continued as needed or required by the community. Another important news for this release is that modifications to the taiga server are no longer required, although there are still two optional patches provided, one to allow inventory management in standalone setup, another to allow for terrain modification using LayerData packages (allows to update a parcels of terrain independently). The old method of uploading and accessing worlds with custom xmlrpc calls is still supported but probably will be discontinued since applying patches to the server is not in most people's reach. Also, I have uploaded a couple of videos: http://www.vimeo.com/user6191106 Testers are wellcome, but note there are still a lof of corners to polish towards a more user focused 1.0. The only worlds tested at the moment are my localhost server, sim.lorea.org server, and virtualexpo world, I would also be happy to test access and compatibility with other worlds. Usage of b2rex is not recommended at the moment with production servers, but it should be safe. For the next release, I intend to add support for logic editing and control in the following areas: 1.Graphical editor for logic 2.Control several logic subsystems from realxtend and opensim 3. Access to the information from blender logic graphs and possibly export it 4.Executing b2rex inside blender's game mode Kudos to Invi, who started the blender2.5 support in this release and also implemented inventory management support.

About any problems regarding running b2rex, you can query me directly, or just ask on irc (irc.freenode.net #realxtend channel), , in the b2rex github or webpage.

[realXtend] b2rex release 0.7: import capabilities
Hi! B2rex 0.7 has been released featuring import capabilities as well as specific character support. The import capabilities allow to browse scene objects directly from blender, update blender objects from realxtend and import whole realxtend regions into blender keeping the uuid link so objects can be synchonized back and forth. More information about the release at: https://sim.lorea.org/pg/blog/group:5/read/401/release-07 Specially, following pages of the manual detail the new capabilities: * https://sim.lorea.org/pg/pages/view/398/ (asset browser) * https://sim.lorea.org/pg/pages/view/400/ (character panel) For next release, I'll be focusing on real time synchronization of blender (to both naali and taiga) and realxtend, support for managing permissions, and adding support for blender2.5 and the new ogre exporter.

For me it was a little bit easier to put the info in a separate file, although this can be changed of course, although the fact is there are uuids for materials, textures, meshes and objects (and I guess more objects, but these are the ones I keep track of right now), so these would have to go in different places if embedded in that way, so the export might be a bit more difficult at least for me, and in some cases might be that we don't have such a place, like with textures or materials, so the separate file approach makes it straightforward in both directions (since we already manage several metadata files anyways). > >> There is still one problem with the approach, though, and it is that I >> didn't manage to make changes to asset data propagate...

Ok, I'll think about updating then, and I'll think about how to overcome the problem. For the moment, though, as b2rex allows to recreate the assets it already works ok to update objects, its just not so efficient as could be and also I'm not sure but I don't see the way assets get deleted from the db so I'm kind of worried :). > >> For the next release, I plan to work on character and animation support, >> also as time allows, I'd like to start work on synchronizing directly to >> naali, and improving any aspects you people think are important, I'd >> specially like to hear feedback on what materials people use or would >> like to use so we can work on making it easy for those. >> > > Right-o.

Yes, also I'd like to hear if people have any problems so don't hesitate to contact me directly on irc for support. Of course regarding materials we're well beyond normalmaps and at the stage of thinking what other techniques might be of interest, so even for people who cannot test right now just think what you would really like to have. My current material "wishlist" is adding some lower end techniques, non-cg techniques, and adding another layer for setting up an ambient occlusion map (or maybe this can be done with the luminance map but I didn't test it yet). More on the toy area, I'd like to try implementing steep parallax or something similar but I haven't tried. > One other thing we've discussed in planning this export stuff, > continuing with the idea of handling updates by keeping the UUIDs, is > allowing editin
[realXtend] b2rex release v0.2
Hi! I packaged a new release for b2rex (blender exporter for realxtend), you can download it at: http://github.com/downloads/caedesvvv/b2rex/b2rex-0.2.zip For this release I focused on improving the material support and allowing updating of objects from blendfiles by maintaining the uuids on the exported objects (for objects, meshes and textures and materials. This means now a blendfile can be kept "linked" to an opensim region in order to keep updating it, which allows to continuously build up a region from one or more blend files, which wasn't really possible before. Note the sync still happens by uploading from blender to modrex, but now the uuids can be maintained. For materials, there is now an interface to preview generated material files and more combinations of the rex supershader are now supported, shadows can be included. So the following texture layers are available for materials now: specularmap, heightmap, normalmap, reflectionmap, opacitymap, shadows. Not all combinations are supported yet due to how the supershader must be used, I've documented working combinations and further information at: https://sim.lorea.org/pg/pages/view/138/. Als a side note, I added parallax support for naali's shader since many of my test maps use it, this can be added to naali, so I can send a patch if this is wanted (its something like 10 lines of cg), for the moment the updated shader files are included on b2rex repo, so people can use them if they want. The parallax technique is cheap but quite effective, although It probably doesn't play so good with shadows. For synchronizing the uuids, I've taken the route of storing uuids with blender objects and including an additional file on the uploaded pack holding the requested uuids. I had to modify the modrex ogre importer for this, the patch is included with b2rex code, and I would like to setup a branch for modrex but its using svn. Maybe we can discuss about this to have this functionality included on modrex. There is still one problem with the approach, though, and it is that I didn't manage to make changes to asset data propagate... I think opensim is not really updating this, so for the moment b2rex supports setting which uuids to keep and which to renew. See the remarks on uuids at the b2rex manual for more information. https://sim.lorea.org/pg/pages/view/86/. Still, metadata is updated properly, so positions and object relations are maintained. I've also setup a test server at http://sim.lorea.org:9000, since b2rex depends on some changes to modrex which still have to be reviewed for inclusion on the server (changing how b2rex accesses things if needed), at least this way people can test the exporter. You can query me for accounts if you want to play there. For the next release, I plan to work on character and animation support, also as time allows, I'd like to start work on synchronizing directly to naali, and improving any aspects you people think are important, I'd specially like to hear feedback on what materials people use or would like to use so we can work on making it easy for those.

Ok, I'll investigate this. The fact is I for maps with exactly the same meshes, like the "monkey heads" test map i'm using (https://sim.lorea.org/pg/photos/view/78/monkey-testmap-with-normalmaps) the first times I uploaded I could only see one of the monkey heads, and now they don't show at all when I connect. This kind of non-deterministic behaviour made me think its something weird like udp connections or mono problems, but yeah, I'll check the db.

The problem with this approach is I can't really maintain connections from blender, or well, I can, but it will be costly in maintenance and stability (it can be done with a cpp module that maintains a thread or with a pseudo thread in python). Normal working of a blender python script is it gets run when the user clicks some button, you can store things on the tool python module, but threads don't survive (well, I haven't tried in some time but last time python threads where not viable solution). Anyways, I want to follow this approach later (i'll start looking at accessing some viewer libraries directly from blender), but I don't think it should be needed for uploading of worlds or interfacing them in a simple way, I can do with session+request-response (ie, rest and xmlrpc). Later sure, I want notifications but in case simple uploading and browsing should work with no cpp libraries to allow people with weird system (ie, without precompiled binaries) to still use blender against taiga to a certain extent (no real time synchro for the "low end" unless I can do it in pure python).

I noticed your code, but since I didn't know how to work with the CAPS protocol I wasn't sure how to use it, anyways, the xmlrpc UploadHandler I've done its very simple, so i'm okay with another approach as long as I can use it from blender (or other tools not inside naali).

Do you have any specific plan already? In the same line, I would also like to be able to create regions from blender (I can with xmlrpc, but It looks like I have to specify the port and ip's manually which is a pain), and upload and download the height map for a region. If we can setup a join plan I can help on this part... also.. since the naali tools you're making are python and so is the b2rex it's likely we can have some common library, also I can code python for naali (well, not yet since looks like I also have some problems with python on naali.. :-)).

[realXtend] Server version to use for development
Hi! I'm trying to setup a recent version of opensim with the latest modrex. Is there any preferred version to use for development? (both for opensim and modrex). I didn't see any mentions on the webpage (well, I did but they look outdated) and modrex readme just points to a recent enough version of opensim, but doesn't specify which.

[realXtend] RealXtend exporter for blender
Hi! I made the first release of a b2rex "exporter": The package is available at: http://github.com/downloads/caedesvvv/b2rex/b2rex-0.1.zip The plugin controls the ogre mesh and scene exporters to generate a world suitable for uploading to realxtend. Also, it can "connect" to the opensim server, and using a custom modrex plugin it can upload worlds and clear a scene directly. Also, i modified the ogre exporters a little bit, to allow whole scene offseting directly, and to improve material handling a little bit, when used with realxtend. It currently supports materials with normalmaps and specularmaps, as well as the normal materials with just a diffuse texture. They are included on the package for now. Note, for direct uploading you need a custom modrex version, and some special config on the server (enable xmlrpc and rest interfaces) Screenshots of exported worlds: https://sim.lorea.org/pg/photos/album/49/exported-worlds More details on the README file, or the manual online: https://sim.lorea.org/pg/pages/view/86/ Also, i setup a webpage for the project: https://sim.lorea.org/pg/groups/5/b2rex/ The page is an elgg instance, and I'd like to configure it to manage a rex grid in the near future, and maybe implement some parts of the asset workflow there. This project is just starting, and comes from a proposal made to nlnet (a dutch fundation) for funding on this regards. They accepted a plan proposal, which is made public at the site webpage. The goal is to have as good blender integration with the realxtend world, also to allow realxtend to have this kind of integration when needed (ie, developing key areas of client or server software). Some people from realxtend already know of this (it was announced on the irc chat some time ago). The plan is pretty far fetched, touching on direct connection from blender, maybe reviewing mesh formats or asset server system, good support for uploading and tweaking characters, great material support, even logic support to the extent possible (or more... ;-)). So, I'm going to be working hard on the next months towards this goals. :-) Anyways, the most important is that I would love to hear any ideas you may have, regarding what can be done from blender or how it can be used. Either on this list or the project webpage. Also, I will be coming back with analysis of the situation to get more direct feedback. On the last weeks I've been getting intimate with the realxtend and opensim software, so there are a lot of things I have to put on paper now for discussion. You can also report problems or bugs in the git repo, or directly on the project forum (or here). Greetings!! Pablo signature.asc Description: OpenPGP digital signature
